Influenza A viruses (IAVs) remain serious threats to public health because of the shortage of effective means of control. Developing more effective virus control modalities requires better understanding of virus–host interactions. It has previously been shown that IAV induces the production of kynurenine, which suppresses T-cell responses, enhances pain hypersensitivity and disturbs behaviour in infected animals. However, the regulation of kynurenine biosynthesis during IAV infection remains elusive. Here we showed that IAV infection induced expression of interferons (IFNs), which upregulated production of indoleamine-2,3-dioxygenase (IDO1), which catalysed the kynurenine biosynthesis. Furthermore, IAV attenuated the IDO1 expression and the production of kynurenine through its NS1 protein. Interestingly, inhibition of viral replication prior to IFN induction limited IDO1 expression, while inhibition after did not. Finally, we showed that kynurenine biosynthesis was activated in macrophages in response to other stimuli, such as influenza B virus, herpes simplex virus 1 and 2 as well as bacterial lipopolysaccharides. Thus, the tight regulation of the kynurenine biosynthesis by host cell and, perhaps, pathogen might be a basic signature of a wide range of host–pathogen interactions, which should be taken into account during development of novel antiviral and antibacterial drugs.

Bacteriophage Adherence to Mucus Mediates Preventive Protection against Pathogenic Bacteria
Almeida, Gabriel M. F.; Laanto, Elina; Ashrafi, Roghaleh; Sundberg, Lotta-Riina (American Society for Microbiology, 2019)Metazoans were proposed to host bacteriophages on their mucosal surfaces in a symbiotic relationship, where phages provide an external immunity against bacterial infections and the metazoans provide phages a medium for ... -
Idiosyncratic effects of coinfection on the association between systemic pathogens and the gut microbiota of a wild rodent, the bank vole Myodes glareolus
Brila, Ilze; Lavrinienko, Anton; Tukalenko, Eugene; Kallio, Eva R.; Mappes, Tapio; Watts, Phillip C. (Wiley-Blackwell, 2023)The effects of systemic pathogens on gut microbiota of wild animals are poorly understood. Furthermore, coinfections are the norm in nature, yet most studies of pathogen–microbiota interactions focus on effects of single ... -
Validation of HT-29 cell differentiation protocol and the use of HT-29 cell model as an infection model
Auramo, Jenni (2023)In vitro -solumallit ovat tärkeitä työkaluja isäntä-patogeeni-vuorovaikutuksen ja mikrobien käyttäytymisen tutkimuksessa, ja niitä tarvitaan erityisesti bakteeritutkimuksessa, sillä nisäkässolumallit vastaavat paremmin in ... -
The effects of Borrelia infection on its wintering rodent host
Sipari, Saana; Hytönen, Jukka; Pietikäinen, Annukka; Mappes, Tapio; Kallio, Eva R. (Springer, 2022)In seasonal environments, appropriate adaptations are crucial for organisms to maximize their fitness. For instance, in many species, the immune function has been noticed to decrease during winter, which is assumed to be ... -
Interactive effects between diet and genotypes of host and pathogen define the severity of infection
Zhang, Ji; Friman, Ville-Petri; Laakso, Jouni; Mappes, Johanna (Wiley-Blackwell, 2012)Host resistance and parasite virulence are influenced by multiple interacting factors in complex natural communities. Yet, these interactive effects are seldom studied concurrently, resulting in poor understanding of ...
